I love this idea. JUST ONE PROBLEM: Even indifference should have some positive consequences. If you are encouraging ROLE-PLAYING, then just having a 'right' and 'wrong' answer doesn't reward being your character.

Your sovereign may have reason to be indifferent, even in seemingly dire situations. Would not a zen master sometimes seem uncaring?

I think being brave should have a downside, as well as benefits. If choices have only expected consequences, there is no drama and no reward for playing as your character.

To paraphrase Robert McKee: "Choices under pressure reveal character."

I think benefits and downside to every choice makes them interesting: you get some benefit you might expect, but unintended consequences rear their head. An 'indifferent' sovereign loses morale among the troops, but might also fare better diplomatically with Ceresa.
